EMC 410063 - Voltaic Arc Welding Processes I

The conventional and pulsed MIG/MAG process with various principles and synergistic and adaptive control. Influence of electrode diameter, factors affecting weld geometry. Modern versions of the MIG/MAG welding process in short-circuit metal transfer (STT, CCC, CMT,...) and free-flight (RapidArc, PCS,..). Orbital MIG/MAG welding for root and fill passes. Orbital TIG welding with open and closed chamber.
